When Ariadne Oliver, the mystery novelist, summons Poirot to join her at a country house in Devon, he is respectful enough of her “intuition” to do so. When she tells him, however, that she is at Nasse House to stage a Murder Hunt at a fête, he is at first peeved that she is wasting his time. But it is not long before he realises that Mrs Oliver's fears are fully justified.
